Abstract

The invention discloses a kind of preparation method of Eucalyptus fire-proof plate, comprise the following steps：(1) Eucalyptus log is processed to the Eucalyptus veneer for being cut into respective thickness；(2) prepared by flame retardant treating agent；(3) Eucalyptus veneer is done into flame retardant treatment；(4) Eucalyptus veneer is done into drying process.Easy to operate, efficiency high of the invention, flame retardant treating agent enters inside Eucalyptus, eucalyptus plate is obtained good fire resistance.

Description

A kind of preparation method of Eucalyptus fire-proof plate
Technical field
The present invention relates to a kind of preparation method of Eucalyptus fire-proof plate.
Background technology
Fire-proof plate demand is larger in the market, and existing multi-layer sheet, glued board combustion heat value are higher, and catching fire temperature is relatively low, flame propagation velocity Quickly, combustible material is belonged to, when these sheet materials meet fire burning, wood plies are peeled off, and carbonization speed is fast, are usually 0.8mm/min~1.3mm/min；Mechanical property is reduced, hygroscopicity increase；Current existing fire-proof plywood can not meet use requirement, at high temperature, Fire retardant promotes wood component dehydration carbonization, is changed into charcoal non activated, the carbonomonoxide concentration caused in smog is increased, the harmfulness in fire hazard aerosol fog Enhancing；Although the fireproof multi-layer board fire line of in the market high-quality has reached national standard, but because non-moistureproof, flatness is bad, deformation, warpage, The problems such as, it is impossible to used in purposes such as furniture, ornament materials, timber, integrated houses.
The content of the invention
It is an object of the invention to provide a kind of preparation method of Eucalyptus fire-proof plate.
A kind of preparation method of Eucalyptus fire-proof plate of the present invention, comprises the following steps：
(1) Eucalyptus log is processed to the Eucalyptus veneer for being cut into respective thickness；
(2) prepared by flame retardant treating agent, is prepared respectively according to following weight proportion：
Fire retardant mixed liquor a：Water, triammonium phosphate, borax proportioning are 100: 25: 20；
Solution b：Water, zinc nitrate proportioning are 100: 30；
Mixed solution c：Water, potassium hydroxide, γ-r-chloropropyl trimethoxyl silane proportioning are 100: 15: 0.5；
(3) Eucalyptus veneer is done into flame retardant treatment：
I, the veneer of moisture content 70% is put into fire-retardant mixed liquor a and soaked 48-50 hour, dried after taking-up, natural drying moisture content below 40%；
II, the moisture content veneer below 30% for obtaining last process, which are put into zinc nitrate liquid b, to be soaked 1-2 hours, is dried, is spontaneously dried aqueous after taking-up Below rate 30%；
III, the moisture content veneer below 30% for obtaining last process, which are put into mixed solution c, to be soaked 1-2 hours, is dried, is spontaneously dried aqueous after taking-up Below rate 25%.
(4) Eucalyptus veneer is done into drying process：The veneer for finishing flame retardant treatment is put into vacuum dryer, dried the veneers within moisture content 10%. The beneficial effects of the invention are as follows：Easy to operate, efficiency high of the invention, flame retardant treating agent enters inside Eucalyptus, eucalyptus plate is obtained good fire-resistant Burning property.
